The two 8-bit ports P0H and P0L represent the higher and lower parts of PORT0,
respectively. Both halves of PORT0 can be written (e.g. via a PEC transfer) without
affecting the other half.
If this port is used for general purpose IO, the direction of each line can be configured
via the corresponding direction registers DP0H and DP0L.
